Abstract:
AD(Axiomatic Design) and TRIZ(Theory of Inventive Problem Solving) are widely used in conceptual design. However, both of the methods have theirs limitations. The integrated model of the two techniques presented in this paper will increase the efficiency and quality of the problem solving process for conceptual design. AD is used for systematically defining and structuring a problem into a hierarchy. Sometime, the design matrix is coupled in AD which indicates the functional requirements are coupled. And TRIZ separation principles can be applied to separate non-independent design parameters, which can provide innovative solutions at each hierarchical level. The improve design of heating and drying equipment in bitumen reproduction device demonstrates that the integrated model can work very well in conceptual design.
